1.5" Ramcats, 1-1/4" Grizz Tricks for deer. I too like a large cutting diameter for deer. Quick kills and short blood trails. I shoot a 525 grain arrow at 280 FPS. I also love the 125 grain 1-1/4" 3 Blade VPA for hogs, very tough head that penetrates great.

Simmons Landshark 165, 1-9/16" cut. Like old killer stated shorter heads are usually more forgiving in the tuning game but with a properly set-up bow and proper fletching you can still get great flight out of a big cut head.

Just seem to be the perfect broadhead for me, I quit looking at other possible broadheads the year I tried them

Arrow placement is the key with any broadhead but the Slick Trick Mag just seems to fit the bill for me better than any of the others I have used over the years. Like Low Fence said, these things fly like laser beams and do unbelievable damage for what looks to be a small head. The only other BH I may concider would be the Slick Trick Grizz Trick that is 1 1/4" making it 2 1/2" cutting surface.

I use Slick Trick Mags (2x1-1/8") and G5s (1.5x1-1/8") for ~25 yards & in and Trophy Ridge Rocket Steelheads (the smaller ones - 1-1/8") for shots out to 40 on spot and stalk hunts or on windy days.
I've found the Slick Tricks whistle quite a bit as they fly and catch a crosswind like a mug!

Rage Extremes work for me. They fly straight and with the new collars rage put on them several years ago they don't open up earlier. Everything I have shot the last 4 years has been dead in under 60'yards. Most closer.
